Combining Discrete and Continous
Posted by ""Geoff McDonnell"" <gmcdonne@bigpond.net.au> Lou In health systems simulation it is not uncommon to use DES/DEV with SD in modeling patient flows esp thru ED, ICU and ORs. DEV matches the way data is collected, but SD better represents the feedback effects associated w...
